Some species are microscopic while others can grow to several meters in length.

1. Algae, first link in the food chain

Bravo! Like plants, algae use mineral salts, water, carbon dioxide and sunlight to grow. They are producers.

2 – Who is a herbivore?

It feeds on algae, such as kelp, using the small teeth located on its underside. This herbivore, or plant-eater, is not dangerous but be careful, it’s prickly!

2. Urchin, the herbivore

Well played! The urchin does not eat other animals. It’s a primary consumer.

3 – Who is the most aggressive predator?

Always ready to attack, it fights its fellow crabs for food. Its two front claws are impressive tools for breaking the shells of its prey.

3. Common rock crab

Super! The common rock crab feeds mainly on animals, making it a secondary consumer.

4 – Who uses its barbels to hunt?

Among fish, the biggest often eat the smallest. This species hunts in the deep, in the dark, using its chin barbel to detect fish and crustaceans hiding in the mud.

4. Atlantic cod

Exactly! Carnivorous fish like the cod eat only animals. Omnivorous fish feed on animal and algae.

5 – Who hunts using its whiskers?

We say it has a horse-shaped head but with its flippers, it’s called a pinniped.

5. Harbour seal

Excellent! Using its very sensitive whiskers, the harbour seal is able to detect its prey (fish, crustacean, mollusc) in total darkness. It’s a carnivore.

6 – Who is a scavenger?

It feeds mainly on dead animal it finds on the sea floor using its siphon-shaped nose.

Right you are! Despite its somewhat unappetizing diet, the whelk’s white flesh is excellent to eat.

Congratulations!

You did it.
